这是我的代码:
import re
t = int(input())
nentry = int(input())
def nitems():
for number in range(nentry):
pt = []
items = input()[:10]
pt.append(items)
if re.match("^[a-z]*$",items):
print(pt)
else:
None
n = nitems()
让我们说一个例子,我会输入:
1
6
same
same
same
different
different
different
我希望它输出复制字符串的次数(基数是1.不介意打印和列表)所以输出应该是:
2
每个字符串的基数为1,输入为三个“相同”字符串,因此副本为两个。 “不同”字符串也是如此。那我该怎么做呢?
答案 0 :(得分:0)
from collections import Counter, defaultdict
t = int(input())
nentry = int(input())
cnt = Counter()
def nitems():
for number in range(nentry):
item = input()
cnt[item] += 1
v = defaultdict(list)
for key, value in sorted(cnt.items()):
v[value].append(key)
for key in v.keys():
print(key)
n = nitems()
演示:
1
4
alpha
alpha
omega
omega
输出:
2
